[00:31:21] <AlecTaylor> _habnabit: I don't have control over the pip command (this is on heroku). All I know is pip does "pip -r requirements.txt"
[00:32:01] <_habnabit> AlecTaylor, pretty sure you can't do that with just requirements.txt unless you pin versions
[00:35:04] <jessamynsmith> AlecTaylor: you can explicitly run pip on heroku
[00:35:14] <jessamynsmith> but if you want to automate this, I think you need to pin the version in requirements.txt
[00:55:28] <AlecTaylor> How do I specify in my requirements.txt to update the package to the latest?
[00:56:57] <dstufft> the answer hasn't changed in 20 minutes, you have to either pin to the latest versions or you have to specify -U on the command line
